2025 Ram 1500 Current Owners - Discussion, Feedback, and Problems

So my 25 limited HO has a CEL on now at 4300 miles. I’ve had one before but went away after a day or so, probably misfire or wrong octane fuel. This time I know something is off…the truck acts like it has no power and the turbo does not exist. I can lay it on the floor and it takes forever to get to 60mph.

I think all it does is turn on front defrost with fan on high and temp to max. I wish it had actual heat in the lower windshield, my wife's Honda pilot does and it works great. Unrelated but the forward facing collision camera does seem to have heat in the windshield right in front of it.

I think it’s actually similar to my Wife’s Highlander where there are rear window type defrost strips/loop under where the wipers rest to free them if they’re icebound.

Did you get under the hood at all? I have a similar issue with a jeep wrangler with the turbo 4 cylinder and it was the boost pressure hose blew off or something stupid once I limped it over to the dealer. may be worth looking in there see if anything came loose..

Am I alone with this? Dead Battery after truck sits for 3 days. 2025 Laramie. 5000 miles. In for service 4 times and it still does it. 1. Replaced the battery, 2. Loose battery cable (sure it was). 3. 10 days in without remedy. 4. Replaced the anti-lock brake module. 5. I have not returned it for service yet.

I have just filed for the Lemon law. I have little faith in the service techs. I searched this forum but no post on this issue.

I haven't seen any other posts recently from people having that issue but that sounds like a parasitic draw on the battery to me... something staying on and not powering down on shut off maybe? I've seen in other forums issues with wireless phone chargers and outlets not shutting off...

The dash periodically wakes up. Yes, parasitic draw. That's why they replaced the brake module.

So the `25s are also suffering from random parasitic draw, good times troubleshooting that.
Would be interesting to know their troubleshooting methodology that led them to the brake module...

My 2 cents for what it is worth....
I bought a DC clamp on amp meter (Klein Tools CL390 AC/DC Digital Clamp Meter, now on sale for $68 on Amazon) to monitor the current when my truck is shut down to see if I am having any parasitic current issues. I would advise you do the same to determine if you are having this issue and how much you are drawing. Typically the parasitic current should be less than 0.05 (50ma) when truck is completely shut down. Keep in mind any of the truck's "Features" that are remote controlled, phone activated, voice activated to bring the truck alive will draw power just to be in that listening state.

Additionally, some of the USBs stay powered after the truck is off. I recommend not having things plugged in those

I know yes there is many threads on your problem.New ones are junk hit or miss.There are many things to do to keep volts up. We should just be able to start and drive off but you can't. My volt will be 14.4 no auto lights or anything auto no wifi shut everything off even touch screen keep keys far away from truck when off.If i turn heat on high all seat warmers defrost and drive fast 13.0 13.3 my volts will be. Something aint right . I know for a fact if my truck sat for days these batteries would die. So slow driving cold start warm up for 4 mins no accessories on volts stay higher. GOOD luck on lemon law let us know how it goes. I wanna take this 80000 dollar paper weight drive it thru the dealership and service mangers house but i love my freedom .

Checked yesterday and everything looked fine

On a different topic: I can’t wait for someone to crack the new CAN Bus encryption (AlphaOBD style). How ridiculous is it that there’s old style cruise control AND adaptive cruise control BOTH available on the steering wheel??? What an accident waiting to happen. Hopefully, when they do crack it, I’ll be able to turn off regular cruise control and the obnoxious triple horn when I get out of the truck with the key in my pocket. Oh, also, I’d turn on Bambi mode.
Thank you for coming to my TED Talk.
